APPARATUS FOB BEGENEBATING AIR. I

To all whom t may concern.'

Be it `known that I, GEORGE voN SCRAP- RINGER, a subject ofthe Emperorof Austria-Hungary, residing at Vienna, Austria- Hungary, have inventedcertain new and useful Improvements'in Regenerating Air, of which thefollowing is a specification.

In rooms or chambers intended for thev inhalation of radium .emanationsit is of importance to regenerate the spent air exhaled by the patientsand to render it again respirable. In accordance with the presentinvention, this regeneration of the spent breathing air is obtained bymeans of an apparatus which is mounted in such rooms or chambers, takesup the exhaled air, cools the same in a refrigerating device and thenlforces it through a medium that absorbs .the carbonic dioxid, whereuponthe thus regenerated air is allowed to be discharged` v again in theroom or chamber.

The apparatus consists essentially of a box or receptacle that isconnected on the one side with an exhauster 0r the like and on the otherside with-the emanation chamber and comprises a cooling device and anabsorption chamber separated from the latter by affiltering layer.

In the accompanying drawings Figure 1 yshows a side elevation of anapparatus according to the present invention, Fig. 2 is a vertical crosssection on the line A-B of Fig. l and Fig. 3 is a plan-thereof with thetop plate removed.

On the base platea is mounted a box b' subdivided by two horizontalpartitions c, d into three superposed cells or compartments. Thelowermost compartment f lined on all sides by perforated metal sheets econtains an electromotor la mounted on a pedestal g and an exhauster ior similar suction device for exhausting the air, driven by the saidelectromotor. The disgharge tube j' of the exhauster opens by means ofan aperture in the partition c into the second box-compartment la whichis closed on all sides. Within this compartment lo is arranged kt-heribbed refrigerator or cooler .l through the pipes of which flows thecooling medium. The spent air forced into this compartment 7c by theexhauster flows along .the outer surface of the ribs of the refrigeratorand becomes cooled. In\ order to maintain the air in intimate contactwith the cooling pipes and the rlbs of the refrig- Specication ofLetters ltatent.

erator, delecting surfaces m may be fitted at suitable places within thecompartment lc between the coolingy pipes l.

compartment lc at the topconsists of two metal platesv d d which arearranged at a certain distance apart and are provided with perforationsand between which is interposed a ilterin cloth d2. The spent air, whichhas been orced 'into the compartment k and has been cooled therein,' butwhich is not yet regenerated, passes through the perforations of themetallic plates d d and the filtering cloth d2 into Athe next highercompartmentn of the box. This walls g g into three' separate sections o,p, o the arrangement `being such lthat the cooled air, coming from thecompartment -c enters only into the two exterior sections 0, o of thecompartment ma The middle section p is intended for holding thereceptacles r which contain and furnish the emanation means, whereas thetwo exterior sections o o are provided with receptacles .s which aremade vof perforated metal plates or of wire cloth bent so as to form aU-shaped cross section `and which are filled with a material capable ofabsorbing carbon dioxid, such as soda-lime or caustic potash. Each ofthe sections o, o is subdivided by the partitions t into separate cellsu and'in each cell u is suspended-a receptacle s in such a manner as toenter with its lower end into a funnel-shaped space m separated from theadjacent spaces by means of the inclined roof-shaped strips fv (Fig. 2).Theaper- 'tures provided in the top-plate d of the partition wall d openinto the said spaces w. The entire apparatus is closed at the top by-means of two perforated metallic plates e e arranged at a certaindistance apart and having a ltering cloth z2 placed between the same.rThe spentair that has been cooled in the compartment c and has beenfreed of impurities by its passage through the filtering layer d2 flowsnow through the absorbing mediumcontained in the receptacle s and 1sAthus freed from carbon dioxid. It then passes through the upperfiltering layer e2 where it is entirely `freed from dust whereupon itreturns again as clear respirL able air into the room or chamber inwhich the inhalation of the emanation means takes The horizontallpartition d which closes the compartment is subdivided by the partitionl 4with absorbing material capable of absorbing the carbon-dioxid in theexhaled air,

andan air filter, closing the apparatus at the top and forming acommunication between the compartment containing the absorption deviceand the surrounding atmosphere.
